- Fix yet another CPU_HOTPLUG problem: instead of calling free_irq()
  on timer halt, just disable the interrupt. On timer restart, detect
  that the interrupt has been requested already and just enable the
  interrupt back. This avoid doing a request_irq() with preemption
  disabled, which triggers an ugly warning. Reported by Stephen Boyd.
